SPAC Offering Forepart, De-SPAC Consummation Timeframe Description [Text Block]

We have until the date that is 24 months from the closing of this offering or until such earlier time as our board of directors may approve, to consummate our initial business combination. If we anticipate that we may be unable to consummate our initial business combination within such 24-month period, we may seek shareholder approval to amend our amended and restated memorandum and articles of association to extend the date by which we must consummate our initial business combination. There is no limit on the number of extensions that we may seek; however, we do not expect to extend the time period to consummate our initial business combination beyond 36 months from the closing of this offering. If we seek shareholder approval for an extension, holders of public shares will be offered an opportunity to vote on the extension and to redeem their shares, regardless of whether they abstain, vote for, or vote against, the proposed extension, at a per share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, including interest earned thereon (net of taxes payable), divided by the number of then issued and outstanding public shares, subject to applicable law. If we are unable to complete our initial business combination and do not hold a shareholder vote to amend our amended and restated memorandum and articles of association to extend the amount of time we will have to consummate an initial business combination within 24 months from the closing of this offering, or by such earlier time as our board of directors may approve, we will redeem 100% of the public shares at a per share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, including interest earned thereon (net of taxes payable and up to $100,000 of interest income to pay dissolution expenses), divided by the number of then issued and outstanding public shares, subject to applicable law and certain conditions as further described herein.

SPAC Additional Financing Plans, Impact on Security Holders [Text Block]

Potential Additional Financings

We may need to obtain additional financing to complete our initial business combination, either because the transaction requires more cash than is available from the proceeds held in our trust account or because we become obligated to redeem a significant number of our public shares upon completion of the business combination, in which case we may issue additional securities or incur debt in connection with such business combination. If we raise additional funds through equity or convertible debt issuances, our public shareholders may suffer significant dilution and these securities could have rights that rank senior to our public shares. If we raise additional funds through the incurrence of indebtedness, such indebtedness would have rights that are senior to our equity securities and could contain covenants that restrict our operations. Further, as described above, due to the anti-dilution rights of our founder shares, our public shareholders may incur material dilution. In addition, we intend to target businesses with enterprise values that are greater than we could acquire with the net proceeds of this offering and the sale of the private placement units, and, as a result, if the cash portion of the purchase price exceeds the amount available from the trust account, net of amounts needed to satisfy any redemptions by public shareholders, we may be required to seek additional financing to complete such proposed initial business combination. We may also obtain financing prior to the closing of our initial business combination to fund our working capital needs and transaction costs in connection with our search for and completion of our initial business combination. There is no limitation on our ability to raise funds through the issuance of equity or equity-linked securities or through loans, advances or other indebtedness in connection with our initial business

combination, including pursuant to forward purchase agreements or backstop agreements we may enter into following consummation of this offering. Subject to compliance with applicable securities laws, we would only complete such financing simultaneously with the completion of our initial business combination. If we are unable to complete our initial business combination because we do not have sufficient funds available to us, we will be forced to liquidate the trust account. In addition, following our initial business combination, if cash on hand is insufficient, we may need to obtain additional financing in order to meet our obligations.

SPAC Offering Forepart, Sponsor Compensation Material Dilution [Flag] true
SPAC, Securities Offered, Redemption Rights [Text Block] We will provide our public shareholders with the opportunity to redeem, regardless of whether they abstain, vote for, or vote against, our initial business combination, all or a portion of their public shares upon the completion of our initial business combination at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account calculated as of two business days prior to the consummation of our initial business combination, including interest earned on the funds held in the trust account (net of taxes payable), divided by the number of then-outstanding public shares, subject to the limitations and on the conditions described herein.  

The amount in the trust account is initially anticipated to be $10.05 per public share. The per share amount we will distribute to investors who properly redeem their shares will not be reduced by the deferred underwriting commissions we will pay to the underwriters. There will be no redemption rights upon the completion of our initial business combination with respect to our Share Rights. Our sponsor, officers and directors have entered into a letter agreement with us, pursuant to which they have agreed to waive their redemption rights with respect to their founder shares, shares underlying the private placement units and any public shares they may acquire during or after this offering in connection with the completion of our initial business combination.

SPAC, Trust or Escrow Account, Material Terms [Text Block]

Nasdaq rules provide that at least 90% of the gross proceeds from this offering and the sale of the private placement units be deposited in a trust account. Of the $155,750,000 in gross proceeds we receive from this offering and the sale of the private placement units described in this prospectus, or $178,475,000 if the underwriters’ over-allotment option is exercised in full, $150,750,000 ($10.05 per unit), or $173,250,000 if the underwriters’ over-allotment option is exercised in full ($10.05 per unit), will be deposited into a trust account in the United States with Odyssey acting as trustee, after deducting $3,000,000 (or $3,450,000 if the underwriters’ over-allotment option is exercised in full) in underwriting discounts and commissions payable upon the closing of this offering and an aggregate of $550,000 to pay fees and expenses in connection with the closing of this offering. The proceeds held in the trust account will initially be invested only in U.S. government treasury obligations with a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 under the Investment Company Act which invest only in direct U.S. government treasury obligations; the holding of these assets in this form is intended to be temporary and for the sole purpose of facilitating the intended business combination. To mitigate the risk that we might be deemed to be an investment company for purposes of the Investment Company Act, which risk increases the longer that we hold investments in the trust account, we may, at any time (based on our management team’s ongoing assessment of all factors related to our potential status under the Investment Company Act), instruct the trustee to liquidate the investments held in the trust account and instead to hold the funds in the trust account in cash or in an interest bearing demand deposit account at a bank. We expect that the interest earned on the trust account will be sufficient to pay taxes. We will not be permitted to withdraw any of the principal or interest held in the trust account, except for taxes payable and up to $100,000 to pay dissolution expenses, as applicable, if any, until the earliest of (i) the completion of our initial business combination, (ii) the redemption of our public shares if we are unable to complete our initial business combination within the completion window, subject to applicable law, or (iii) the redemption of our public shares properly submitted in connection with a shareholder vote to approve an amendment to our amended and restated memorandum and articles of association (A) to modify the substance or timing of our obligation to allow redemption in connection with our initial business combination or to redeem 100% of our public shares if we have not consummated our initial business combination within the completion window or (B) with respect to any other material provisions relating to shareholders’ rights or pre-initial business combination activity.

SPAC, Compensation and Securities Issuance, Material Dilution, Likelihood [Text Block]

The difference between the public offering price per unit and the NTBV per Class A ordinary share after this offering constitutes the dilution to investors in this offering. NTBV per share is determined by dividing our NTBV, which is our total tangible assets less total liabilities (including the value of Class A ordinary shares that may be redeemed for cash), by the number of outstanding Class A ordinary shares. See the section “Dilution.”

De-SPAC, Material Potential Source of Future Dilution, Description [Text Block]

The below calculations (A) assume that (i) no ordinary shares are issued to shareholders of a potential business combination target as consideration or issuable by a post-business combination company, for instance under an equity or employee share purchase plan, (ii) no ordinary shares and convertible equity or debt securities are issued in connection with additional financing that we may seek in connection with an initial business combination, and (iii) no working capital loans are converted into private placement units, as further described in this prospectus, and (B) assume the issuance of (i) 15,000,000 Class A ordinary shares (or 17,250,000 Class A ordinary shares if the over-allotment option is exercised in full) and 5,750,000 founder shares (up to 750,000 of which are assumed to be forfeited in the scenario in which the over-allotment option is not exercised in full) and 575,000 private placement shares (or 597,500 private placement shares if the underwriters’ over-allotment option is exercised in full) and (ii) 1,500,000 Class A ordinary shares (or 1,725,000 Class A ordinary shares if the over-allotment option is exercised in full) underlying the public rights and 57,500 Class A ordinary shares (or 59,750 Class A ordinary shares if the over-allotment option is exercised in full) underlying the private placement rights. Further, the issuance of additional ordinary or preference shares may significantly dilute the equity interest of public shareholders, which dilution would even further increase if the anti-dilution provisions in the Class B ordinary shares resulted in the issuance of Class A ordinary shares on a greater than one-to-one basis upon conversion of the Class B ordinary shares.

(1)      Expenses applied against gross proceeds include offering expenses of approximately $550,000 and underwriting commissions of $3,000,000 (or $3,450,000 if the underwriters’ option to purchase additional units is exercised) (excluding deferred underwriting commissions). See “Use of Proceeds.”

(2)      Upon the consummation of our initial business combination, $0.40 per unit (up to $6,000,000 or up to $6,900,000 in the aggregate if the underwriters’ over-allotment option is exercised in full) will be payable to the underwriters for deferred underwriting commissions on amounts remaining in the trust account after all redemptions by public shareholders have been met.

(3)      If we seek shareholder approval of our initial business combination and we do not conduct redemptions in connection with our initial business combination pursuant to the tender offer rules, our sponsor, initial shareholders, directors, executive officers or their affiliates may purchase shares or public Share Rights in privately negotiated transactions or in the open market either prior to or following the completion of our initial business combination. In the event of any such purchases of our shares prior to the completion of our initial business combination, the number of Class A ordinary shares subject to redemption will be reduced by the amount of any such purchases, increasing the pro forma net tangible book value per share.
